Comparative reviews

I'd like to suggest that the equipment reviews could include some comparative information.

For example, the January 2016 edition has a review of the Celestron Omni XLT AZ 102 telescope package, with a stated price of £325. This is not too dissimilar to the price point, circa £349, of the Celestron 102SLT. The Omni AZ102 is an F6.5 (102mm by 660mm) refractor on a manual alt-az mount with tripod. The 102SLT is an F6.5 (102mm ...

Skywatcher Evostar 120

What can i say about it,wow a brilliant long focal length scope for the price.Compared to my old 6 inch i would say the 120 was better.Best designed for moon and planets but equally at home on DSO's,although i does'nt perform well on deep sky imaging with a DSLR over a faster scope.The rack and pinion focuser is very smooth and the new black and white paint work make the scope look more expensive than ...

Nov 'Group Test Winner'

Anyone know where Nov '10 'Group Test Winner' : Meade NGC 70 AZ - can be purchased from? Telescope House confirm they won't have any until August 2011. Harrison Telescopes stock the NG, but not the NGC. Evergreen Optics don't appear to stock the NGC either. Optical Vision and David Hinds aren't Meade stockists. Searches for it abroad (.de, .com, .fr etc.) so far have been fruitless, as none of them will ship to the ...

What am I missing re Exit Pupil size?

As you can see from my other post, there are some things about the September Group Test which I don't understand. The Hyperion 3.5mm is criticised for having a small exit pupil, whereas the Orion 3.7mm is praised for having "a sensibly wide exit pupil". I thought that in the same telescope the only thing determining exit pupil was the EP focal length. Since the focal lengths of the two EPs are very similar I ...
